IMPROVEMENT IN CORN-PLANTERS.

The Schedule referred to in these Letters Patent and making part of the same.

vlb all whom "it may concern:

' of reference marked thereon.

This invention relates to certain improvements in seed-planters; and

It consists-'- First, in the manner of opening the ground for the reception of the seed;

Second, in certain devices for deliveringthe seed; and

Third, in the manner of covering it.,

Other points, of minor importance, are believed to be novel, all of which .will be fully described hereinafter.

In the drawings- I Figure 1 is a plan view-of my invention;

Figure 2 is a side elevation; 7 Figure 3 is a plan view of the bottom of the hopper; and

Figured, atransverse section of one of the disks 0.

To enable those skilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation.

A'represents the front bar of the machine, to which the team is attached.

B B represent bars extending rearwardly fromthe bar A, to which are attached the earth -openers, or plows.

O G represent standards, rising perpendicularly from bar A, to which are rlgidly attached the front ends of handles D, which latter are also connected with bars B, by means of the standards d d. By this construction, it will be observed that the handles D and bars- A, B B, are rigidly connected together, and form what may be called the main frame of the machine.

E E represent arms extending rearwardly from the upper ends of thestandards O G, which are connected together at their rear ends'by means of the bar E.

These arms are pivoted to the standards 0 O, and, with the bar E, form an adjustable frame.

E represents a shaft, turning in hearings in the arms E E, upon which is placed the wheel E Upon the ends of shaft E are the disks 6 e, which have in their faces the seed-cups e 0. These cups are regulated to sow a greater or less quantity, by means of a screw, the head of which forms the bottom of the cup. By turning this in or out, the cup is made to hold more or less, as may be desired.

F F represent hoppers, located over the disks 6 e, which have the conducting-spouts ff, leading into the deliverv-snouts b b upon the bars B.

Within the hoppers F F are rubber bushings, f, against which thedisks turn. These bushings are made dovetailing in form, and are fitted into corresponding sockets in the bottom of the hopper. They also are secured in place by a metal plate, as shown.

B B represent the earth-openers, which are constructed of a triangular, wedge-shaped form, being intended, not to cut open the earth, but crowd' it to, either side. The rear, and wider part of the opener, is cut away at the bottom, so that the seed is delivered at the rear end, the opener, in fact, forming a continuation of the delivery-spouts, so that the seed is not ex; posed at all after it enters the hopper.

H H represent the coverers, which consist'of a pair,

of curving blades, of the shape shown, which flare outward from each other slightly at the rear ends.

I represents a scraper upon the bar E, by means of which the wheel is cleaned.

J J represent hinged markers, attached to the extreme ends of the bar A, by means of which, the ground is laid off.

The operation of my machine is as follows:

In moving over the field, the wheel turning upon the ground, gives motion to the shaft, by means of which the seed is regularly delivered to the spouts. The earthopeners make a firm, deep furrow, in which the seed is deposited, and almost immediately hidden. by the coverers The operator, holding the handles, has complete con trol of the machine. His position is ,such, also,- that he can see the seed as-it is deposited, and thus be sure that the machine is operating.

The markers lay off the ground for the next passage of the machine.

'The hinged frameperm'its the wheel to pass over inequalities of sin'face, without affecting the main part of the machine.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent of the United States, is-

1. The adjustable frame E E, constructed and arranged as described, with its shaft, wheel, and hoppers, in combination with the main frame A B G D.

2. The seed-planter described, consisting of the main frameA B O D, adjustable frame E E, with its at-
